You can do it with Alacon - command-line utility for Alasql database.

It works with Node.js, so you need to install Node.js and then Alasql package:

To take data from Excel file you can use the following command:

> node alacon "SELECT * INTO XLSX("main.xls",{headers:true}) 
               FROM XLSX('data1.xlsx', {headers:true}) 
               UNION ALL SELECT * FROM XLSX('data2.xlsx', {headers:true})
               UNION ALL SELECT * FROM XLSX('data3.xlsx', {headers:true})
               UNION ALL SELECT * FROM XLSX('data4.xlsx', {headers:true})
               UNION ALL SELECT * FROM XLSX('data5.xlsx', {headers:true})"

This is one very long line. In this example all files have data in "Sheet1" sheets.
